Bust 100%
In order to achieve 100 percent completion on a mission, you have to play on the Brutal difficulty setting. Complete all primary and secondary objectives, kill every single enemy and find the hidden DNA sequence. Also, you can't allow any of your teammates to die.
Earning Medals
At the mission select screen, you'll see four spots for medals. The first three spots are filled when you beat the mission on Standard, Hard and Brutal. The fourth is filled when you find the hidden DNA sequence. If you've completed all objectives and killed all enemies, the medal will be gold. If not, it will be silver.
Easy Attacking
Use your other characters to support you at the flanks, this will make it easy for you to attack.
Easy powerups at lava levels
You can get easy ammo, grenades, and medpaks in those lava levels(the first lava level you get Hawk)by going those little blue huts the caammander guy says something like "i got a good signal on this place" then powerups come up. Then whenever you go in a little blue huts powerups come.
Further Grenade Distance
Get any type of grenade look straight up slightly look towards where you want to chuck it and hold the left trigger down and let it fly. It should go further but it isn't that accurate.
How to beat the final boss
The final boss at first may be difficult but he really is easy. Get near the shield that he teleports him self to. If you look around near there you will see those generator things you had to shoot earlier in the mission. Shoot them all and then go to were the console is in the middle of the area your in. When he teleports back to the shield was, activate the console and a meteor will crash into him killing him.
Regenerating
Here's a little cheat to regenerate your teammates. If you're on your last guy, insert another three controllers into your Xbox and press start. As new players join, your teammates will be brought back to life. Now just quit out of the three games you just opened and you'll go back to single player mode, but your teammates will remain.
